Mind games for mind exercise

Who doesn’t want to have a sharp mind? Having a sharp mind is something we all want. I recently read a thought-provoking article about it entitled Cognitive Fitness in Harvard Business Review. The article talks about how the minds of people like Warren Buffet and Alan Greenspan stay sharp even in their old age.

What is the secret? The secret is brain workout. They exercise their brain continuously and that makes their minds sharp.

One way to exercise your brain is playing:

Play engages the prefrontal cortex, responsible for your highest-level cognitive functions – including self-knowledge, memory, mental imagery, and incentive and reward processing… Activities like bridge, chess, sudoku, role-playing games, and challenging crossword puzzles all provide rigorous neural workouts.

Looking at myself, I must admit that I do not play as much as I should. So I went around the web and searched for places where I can play games to have fun and exercise my brain. What I want are places where I can play for free and – whenever possible – play alone without having to find partners first. This way I can easily exercise my mind whenever I want.
